T0 on whom, it may concern.-

Be it known that I, FREDERICKE. STANLEY, 'a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented a certain new and useful Improvement in Button- Setting Machines, of which the following is a full, clear, and exact description.

This invention relates to machines for applying buttons to garments by means of tacks and similar metal faste'nings, and has special reference to the means for presenting the fastenings to the plunger or setting device like parts are similarly designated, Figure 1" is a side elevation of the head of one form of machine embodying my invention. Fig. 2 is a front elevation thereof. Fig. 3 is a front perspective view of the spring-pressed jaws detached and in condition to receive the fastening. Fig. 4 is a rear perspective view of the spring-pressed jaws detached and in condition to discharge the fastening. Fig. 5 is a top plan view of the said jaws detached.

The base a, the anvil mechanismb, the

gooseneck c, hopper d for containing and feeding the fastenings, such as tacks, the raceway e for delivering the tacks to the tackholder, the hopper-actuating mechanism f, the vertically-reciprocating plunger g, its actuating-lever h, the tack-switch 2', and its actuating mechanism may be of any usual or, as shown, preferred construction and need no further description forthe purposes of this specification excepting to note that the hopper-actuating mechanism, consisting, es-

sentially, of a pawl and ratchet, is controlled by a lever j,vibrated b'y the'lever h, and the switch is vibrated by a rod is, connected with the ratchet and deriving motion therefrom. The'mechanism described serves to feed a tack to the tack holder, herein shown as spring-pressed jaws, presenting it point down to the said holder, by which, in conjunction with the plunger, it is presented to a button bottom up in the anvil and affixed to the garment which is placed over the button, the holder meanwhile freeing or delivering the tack and receding from the anvil and again going back into position to receive another tack for the repetition of these operations.

The tack-holder is composed of a pair of jaws l of complemental construction,pivotally jointed at their upper ends, as by a screw m, and having adjacent parallel cut-away portions to form a slot 12, and their lower ends 0 arranged at right angles and provided with complemental countersunk recesses to form an opening 19 to receive and support a tack by its "head and with its point downward. These jaws are normally closed, as in Figs. 1, 2, 3, and 5, by means of a spring 1' or equivalent device attached to and carried by them. These jaws are mounted upon the head of the gooseneck by means of screws 8 and 25, one or both of which may be provided with a washer u, interposed between its headand the jaws and of a diameter commensurate with remaining in engagement withthe jaws in the spread of the jaws in discharging a tack. The jaws are capable of vertical movement upon the head, and such movement is limited by the screws 3 and tin their relative arrangement withinthe slot 01. and by pins 1; on the jaws, which come into contact with the head. The jaws are normally elevated, as in Figs. 1 and 2, by a spring 10, supported upon a pin agrising from the head or gooseneck. As a tack is delivered to the holder from the raceway with its point down, the plunger 9 is caused to descend, and coming into contact with the head of the tack within thej aws and firmly holding it therein it carries down the jaws until the pressure overcomes the jaw-spring or until their descent is arrested by the screw 8 coming into contact with the upper end of the slot at, and the plunger in its further descent pressing upon the jaws causes them to separate or swing apart or open laterally against the tension of the spring 4, whereby the tack is released and is free to be acted upon by the plunger to connect it with the button by upsetting its point within said button in any usual way. The parts are timed to release the tack by the opening of the jaws at the time when the tack-point has pierced the garment and entered the button, or thereabout, and so that the tack will remain upright when unsupported by the jaws and in position to be set by the plunger. As soon as the jaws fully separate or open and are thus freed from the pressure of thedescending plunger they rise under the tension of spring to and resume their normal position opposite the discharge end of the raceway, and when the plu nger completes its return stroke and clears the jaws said jaws come together again un der pressure of spring 7* and are ready to receive the next tack for the repetition of these operations. Thus a very simple and eflicient tack-holder is provided for this class of button-setting machines.

tack-holder consisting of a pair of jaws directly pivoted together at their upper ends, and having their lower portions extending beneath the head and in the line of movement of the plunger and adapted to receive and support a tack with its head uppermost, and a spring normally closing said jaws, said tack-holder being mounted to slide on the outer front face of the head of the machine, the movement of the tack-holder for placing a tack being effected by contact of the plunger therewith as it descends and the parting of the jaws to release the tack also being offected by said plunger in its further descent, and means for normally drawing up the tackholder and serving to retract it as the plunger ascends.

In testimony whereof I have hereunto set my hand this 20th day of August, A. D. 1901.

FREDERICK E. STANLEY.
